Reptiles and Frogs of Durokoppin and Kodj Kodjin V REPTILES AND FROGS OF DUROKOPPIN AND J{ODJ KODJIN NATURE RESERVES JOHN DELL and A. CHAPMAN Reptiles and frogs were collected on Durokoppin (DR) and Kodj Kodjin Reserves (KKR) between 8-17 October 1975 and 8-15 April 1976. A few specimens were collected on 26-27 January 1977. Specimens were collected by similar methods to those outlined by Chapman & Dell (1978). For location and deta Is of Reserves see Muir (this report). Specimens caught (R56497-56663) are in the Western Australian Museum. Measurements are in millimetres. LEPTODACTYLIDAE Heleioporus albopunctatus DR.

    Rec. West. Aust. Mus., 1978,6 (3) TAXONOMIC NOTES ON THE REPTILES OF THE SHARK BAY REGION, WESTERN AUSTRALIA G.M. STORR* I.Received 24 March 1977. Accepted 5 May 1977. Published 30 Junc 1978.\ ABSTRACT Two new pygopodid lizards (Pletholax gracilis edelensis and Aprasia haroldi) and two new skinks (Lerista planiventralis decora and Menetia amaura) are described. Ctenotus youngsoni, C. alieni and C. mimetes are redescribed. Additional data are provided for Amphibolurus maculatus bad ius, Lerista macropisthopus, L. lineopunctulata, L. nichollsi and Vermicella littoralis. INTRODUCTION A generous grant from Mr and Mrs W.H. Butler enabled the Western Australian Museum to send two collectors, Messrs G. Harold and M. Peterson to the Shark Bay region for four weeks in August and September 1976. The grant also covered Mr Harold's expenses in the laboratory during the registra­ tion of the collection. Strangely, less was known of the fauna of the Shark Bay mainland than of the adjacent islands. Harold and Peterson therefore concentrated on sampling all major habitat types on Edel Land, the Peron Peninsula and the coastal plains south and east of Hamelin Pool. Their 751 specimens were distributed among 74 species and subspecies as follows: Leptodactylidae - Arenophryne rotunda (1) Hylidae - Litoria rubella (4) Cheluidae - Chelodina steindachneri (2) Gekkonidae - Crenadactylus ocellatus (28), Diplodactylus alboguttatus (40), D. michaelseni (7), D. pulcher (2), D. spinigerus (29), D. squarrosus * Department of Birds, Reptiles and Amphibians, W.A.

  • Molecular Evidence for Gondwanan Origins of Multiple Lineages Within A
    Journal of Biogeography (J. Biogeogr.) (2009) 36, 2044–2055 ORIGINAL Molecular evidence for Gondwanan ARTICLE origins of multiple lineages within a diverse Australasian gecko radiation Paul M. Oliver1,2* and Kate L. Sanders1 1Centre for Evolutionary Biology and ABSTRACT Biodiversity, University of Adelaide and Aim Gondwanan lineages are a prominent component of the Australian 2Terrestrial Vertebrates, South Australian Museum, North Terrace, Adelaide, SA, terrestrial biota. However, most squamate (lizard and snake) lineages in Australia Australia appear to be derived from relatively recent dispersal from Asia (< 30 Ma) and in situ diversification, subsequent to the isolation of Australia from other Gondwanan landmasses. We test the hypothesis that the Australian radiation of diplodactyloid geckos (families Carphodactylidae, Diplodactylidae and Pygopodidae), in contrast to other endemic squamate groups, has a Gondwanan origin and comprises multiple lineages that originated before the separation of Australia from Antarctica. Location Australasia. Methods Bayesian (beast) and penalized likelihood rate smoothing (PLRS) (r8s) molecular dating methods and two long nuclear DNA sequences (RAG-1 and c-mos) were used to estimate a timeframe for divergence events among 18 genera and 30 species of Australian diplodactyloids. Results At least five lineages of Australian diplodactyloid geckos are estimated to have originated > 34 Ma (pre-Oligocene) and basal splits among the Australian diplodactyloids occurred c. 70 Ma. However, most extant generic and intergeneric diversity within diplodactyloid lineages appears to post-date the late Oligocene (< 30 Ma). Main conclusions Basal divergences within the diplodactyloids significantly pre-date the final break-up of East Gondwana, indicating that the group is one of the most ancient extant endemic vertebrate radiations east of Wallace’s Line.

To date, the numerous islands off the coast have been little surveyed. We surveyed 24 of the largest islands along the Kimberley coast for reptiles between 2007 and 2010, to improve our understanding of biogeographical patterns of the region and to locate populations of species that may be threatened by factors including changed fi re regimes and Cane Toad invasion. We recorded 79 species of terrestrial reptiles. Species richness ranged from 14 to 32 taxa per island (mean = 22), and tended to increase with island area. Many taxa (36.7%) were Northern Kimberley endemics, 10 of which are only known from island populations. There were numerous new records for islands, range extensions and the discovery of at least three new taxa. Classifi cation based on species presence/absence data identifi ed several distinct clusters of islands, with geographical location of islands, extent of rugged, rocky habitat and climatic gradients at a regional scale having important infl uences on reptile communities.

These sitE's were not overtlv affected by secondarv salinisation, but did include sites that were 'natu~ally' saline. We recorde~i a total of 144 species from 74 genera and 15 families. There was an average of 10.4 species per quadrat with a range from one to 19. Vertebrate species richness was highest on dissection valley floors and sandy depositional surfaces of the 'old plateau' but lowest on saltflats. Total species richness was positively correlated with high levels of sand, with low levels of soil nutrients and with good soil drainage. When frogs, reptiles and mammals were considered separately, temperature and rainfall attributes were also shown to exhibit correlations with species richness. Patterns in species composition could be explained in terms of climatic and substrate variables, including salinity. Two distinct faunas were identified - one concentrated in the semi-arid northern and inland parts of the study area, and one concentrated in the more mesic south and south-east.

  • Purnululu National Park
    World Heritage Scanned Nomination File Name: 1094.pdf UNESCO Region: ASIA AND THE PACIFIC __________________________________________________________________________________________________ SITE NAME: Purnululu National Park DATE OF INSCRIPTION: 5th July 2003 STATE PARTY: AUSTRALIA CRITERIA: N (i)(iii) DECISION OF THE WORLD HERITAGE COMMITTEE: Excerpt from the Report of the 27th Session of the World Heritage Committee Criterion (i): Earth’s history and geological features The claim to outstanding universal geological value is made for the Bungle Bungle Range. The Bungle Bungles are, by far, the most outstanding example of cone karst in sandstones anywhere in the world and owe their existence and uniqueness to several interacting geological, biological, erosional and climatic phenomena. The sandstone karst of PNP is of great scientific importance in demonstrating so clearly the process of cone karst formation on sandstone - a phenomenon recognised by geomorphologists only over the past 25 years and still incompletely understood, despite recently renewed interest and research. The Bungle Bungle Ranges of PNP also display to an exceptional degree evidence of geomorphic processes of dissolution, weathering and erosion in the evolution of landforms under a savannah climatic regime within an ancient, stable sedimentary landscape. IUCN considers that the nominated site meets this criterion. Criterion (iii): Superlative natural phenomena or natural beauty and aesthetic importance Although PNP has been widely known in Australia only during the past 20 years and it remains relatively inaccessible, it has become recognised internationally for its exceptional natural beauty. The prime scenic attraction is the extraordinary array of banded, beehive-shaped cone towers comprising the Bungle Bungle Range. These have become emblematic of the park and are internationally renowned among Australia’s natural attractions.

    Comparative phylogeography and diversity of Australian Monsoonal Tropics lizards Rebecca Jan Laver ORCID ID 0000-0002-6319-7213 Doctor of Philosophy January 2017 The School of BioSciences Faculty of Science The University of Melbourne Submitted in total fulfilment of the requirements of the degree of Doctor of Philosophy Produced on archival quality paper Thesis Abstract Tropical savannah biomes cover ~20% of the world’s landmass, however the biodiversity encompassed within these environments and the underlying processes that have shaped it remain poorly understood. Recent increased research to address this knowledge gap have begun to reveal surprisingly high amounts of deep, geographically- structured diversity, much of which is cryptic or hidden within morphologically similar species complexes. These patterns are especially emphasized in vertebrate taxa which are intrinsically linked to rock escarpments and ranges that dissect the savannah woodlands and grasslands of many of these biomes, hinting at a role of heterogeneous topography in structuring diversity. The remote Australian Monsoonal Tropics (AMT) spanning the north of the Australian continent is a particularly vast, and relatively undisturbed, tropical savannah region. Recent increased surveys are revealing numerous new species and endemism hotspots, indicating we are only just beginning to uncover the true biodiversity levels within this biome. Not only is there a relative paucity of knowledge regarding the present diversity within this region, but there is also limited understanding of how this diversity came to be. Phylogeographic studies can assist us in establishing current patterns of diversity and their evolutionary significance within regions and biomes. Furthermore, by comparing and contrasting the patterns and timing of diversification within and between biomes for multiple ecologically diverse taxa, we can begin to elucidate the history of these biomes and the environmental processes that have shaped the diversity we observe today.

  • Reptiles of Dirk Hartog Island Mark Cowan (October 2018)
    Reptiles of Dirk Hartog Island Mark Cowan (October 2018) Dirk Hartog Island has a rich reptile fauna with over 40 species recorded. This is more species than most other Western Australian islands which is probably due, in part, to the large size of the island (620 km2), and to the relatively short time it has been isolated from the mainland. The species recorded on the island include four dragons (Family Agamidae), eight geckos (families Carphodactylidae, Diplodactylidae and Gekkonidae), five legless lizards (family Pygopodidae), fifteen skinks (family Scincidae), one goanna (family Varanidae), eight front fanged snakes (family Elapidae), one python (family Pythonidae) and one blind snake (family Typhlopidae). While no species are endemic to the island, a number are endemic to Western Australia with several of these having distributions restricted along the adjacent Western Australian coast or to the Shark Bay area. Species confined more or less to the Shark Bay area are Ctenophorus butloreum (Shark Bay Heath Dragon), Aprasia haroldi (Shark Bay Worm-Lizard), Ctenotus youngsoni (Shark Bay Sand Ctenotus) and, Lerista varia (Variable-striped Robust Slider). A fifth species, Egernia stokesii (Stokes’ Skink) has a subspecies (Egernia stokesii badia) occurring on Dirk Hartog Island that is a threatened species; listed as vulnerable under the WA Biodiversity Conservation Act 2016 and as endangered under the Commonwealth Environment Protection and Biodiversity Conservation Act 1999. It is a relatively large and robust skink covered in small spiny scales and is approximately 190mm head-body length. It usually occupies rocky environments or hollow logs. The following pages show all but one of the recorded species, Demansia calodera (black-necked whipsnake).
